答案與解析：
1. D. 此處can表示 “能力”。
2. A. 此處can表示推測(cè)“可能”的意思;have to表示“不得不”，強(qiáng)調(diào)客觀情況。
3. B.此處can表示允許，許可。
4. D. 在表示能力時(shí)，can(could)和be able to在很多情況下能夠互換，但在下列情況下只能用be able to: ①位于助動(dòng)詞后;②位于情態(tài)動(dòng)詞后;③表示成功地做了某事。本題即屬于第三種情況。
5. A. could have done用于肯定句中表示本來(lái)能夠做成某事但結(jié)果沒(méi)能做成，含有遺憾的意味，側(cè)重有能力而沒(méi)有能做成。
6. B. may not表示“可能不”，表示不太確定的推測(cè)。
7. B. mustn’t表示“禁止”，may表示不太確定的推測(cè)。
8. D. 這里must表示必要性，意為“必須，一定要”。
9. D. must have done表示對(duì)過(guò)去發(fā)生的事情的肯定推測(cè)，意為“想必，準(zhǔn)是，一定是”
10. A. can/could not have done表示對(duì)過(guò)去的否定推測(cè)“不可能做過(guò)……”。
11. B. must have been doing表示對(duì)過(guò)去進(jìn)行時(shí)態(tài)或者過(guò)去完成進(jìn)行時(shí)態(tài)的肯定推測(cè)。
12. A. shall用于主語(yǔ)為第一、三人稱的疑問(wèn)句中表示建議、征求對(duì)方意見(jiàn)時(shí)，其回答一般用“Yes, you must.”或“ No, you needn’t.”。
13. D.在主語(yǔ)為第二、三人稱的肯定句中，shall表示決心、許諾、命令等。
14. D. should指“應(yīng)該”，表示命令、勸告或建議等。
15. C. 在某些名詞性從句中，should可以表示驚異、意外等情況，意思是“竟然”。
16. C. should /ought to have done“表示本該做某事卻未做”，其否定形式shouldn’t /ought not to have done則表示“本不該做某事卻做了”。
17. B. 本句表示本不該做某事卻做了。
18. C. will與第一人稱連用表示意愿、意志。其它選項(xiàng)則不能表示意愿。
19. A. would表示過(guò)去習(xí)慣性的動(dòng)作。
20. C. used to表示“過(guò)去的習(xí)慣動(dòng)作或狀態(tài)(現(xiàn)在 已不這樣)”，其后接動(dòng)詞原形。
21. C. 選項(xiàng)A表示“不能、不許”;B表示“不行、禁止”;C表示“不必、不需要”;D為“不應(yīng)該”。
22. C. needn’t have done表示過(guò)去本不必做某事而實(shí)際已做了某事，強(qiáng)調(diào)“不必要”，其肯定式need have done則表示過(guò)去本需要做某事而實(shí)際上未做。
23. D. dare作實(shí)義動(dòng)詞時(shí)其后的不定式可帶to，也可以不帶to，此句中的實(shí)義動(dòng)詞dare的時(shí)態(tài)應(yīng)為一般過(guò)去時(shí)態(tài)。
24. B. had better表示“最好……”，后接動(dòng)詞原形，其否定式為“had better not”.
25. B. 能夠表示“寧愿、寧可”意思的就只有B。
